There is no more volatile and sensitive an issue for Beijing than the U.S. military presence in the Taiwan Strait which China considers its own dominance area.
Yet the U.S. Navy for the first time since 1969 has re-established its routine presence in the 100-mile wide strategic choke-point, much to China’s frustration.
The Taiwan Strait is considered a front-line region for China to cross in its repeated vows to “liberate” or invade Taiwan which Beijing claims as its own sovereign territory.
The communist government has attempted to invade Taiwan since 1949. In July 1950, President Harry S. Truman ordered the Japan-based U.S. 7th Fleet to operate a constant naval patrol in the Taiwan Strait to prevent China’s military actions against Taiwan.
In 1995 and 1996, the Chinese military launched a military intimidation campaign against Taiwan’s first ever democratic presidential election.
